Mishkat al-Masabih 5017 — Manners

Anas Narrated from:

A man passed the Prophet صلى الله عليه وسلم while many people were with him. A man among those who were with the Prophet صلى الله عليه وسلم said, 'Surely I love this man for the sake of Allah." So, the Prophet صلى الله عليه وسلم asked, "Have you informed him of it?" He said, "No" And, he instructed him, "Get up! Go to him and inform him." So, he arose (from the assembly of the prophet صلى الله عليه وسلم) and went up to him, and informed him. The man said (by way of prayer), "May he love you for whose sake you love me!"The man then returned and the Prophet صلى الله عليه وسلم asked him (how he reacted), and he told him what the man's answer was. The Prophet صلى الله عليه وسلم said, "You shall be (in the hereafter) with the man whom you love and you shall have reward (for it and every deed) you sought from Allah." [2] Another version (in Tirmidhi) is that he said, "A man shall be with him whom he loves and shall receive what he has earned." [3]
